ACCOUNTING POLICIES | |
The condensed consolidated financial statements include the accounts of Cincinnati Financial Corporation and its consolidated subsidiaries, each of which is wholly owned. These statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation. | |
The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Our actual results could differ from those estimates. Our December 31, 2013, condensed consolidated balance sheet amounts are derived from the audited financial statements but do not include all disclosures required by GAAP. | |
Our March 31, 2014, condensed consolidated financial statements are unaudited. Certain financial information that is included in annual financial statements prepared in accordance with GAAP is not required for interim reporting and has been condensed or omitted. We believe that we have made all adjustments, consisting only of normal recurring accruals, that are necessary for fair presentation. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our 2013 Annual Report on Form 10-K. The results of operations for interim periods do not necessarily indicate results to be expected for the full year. |

The net unrealized investment gains in our fixed-maturity portfolio are primarily the result of the continued low interest rate environment that increased the fair value of our fixed-maturity portfolio. The five largest unrealized investment gains in our common stock portfolio are from Exxon Mobil Corporation (NYSE:XOM), The Procter & Gamble Company (NYSE:PG), Honeywell International Incorporated (NYSE:HON), Chevron Corporation (NYSE:CVX), and Dover Corporation (NYSE:DOV), which had a combined gross unrealized gain of $431 million. At March 31, 2014, we had $17 million fair value of hybrid securities included in fixed maturities that follow Accounting Standards Codification (ASC) 815-15-25, Accounting for Certain Hybrid Financial Instruments, compared with $18 million fair value of hybrid securities at December 31, 2013. The hybrid securities are carried at fair value, and the changes in fair value are included in realized investment gains and losses. | |||||||||||||||||||||||||

During the three months ended March 31, 2014 and 2013, there were no credit losses on fixed-maturity securities for which a portion of other-than-temporary impairment (OTTI) has been recognized in other comprehensive income. | |||||||||||||||||||||||||
During the quarter ended March 31, 2014, there were two equity securities and one fixed-maturity security other-than-temporarily impaired. At March 31, 2014, ninety-nine fixed-maturity investments with a total unrealized loss of $19 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity investments had fair values below 70 percent of amortized cost. One equity investment with a total unrealized loss of less than $500,000 had been in an unrealized loss position for 12 months or more as of March 31, 2014. This equity investment was not trading below 70 percent of cost. | |||||||||||||||||||||||||
During 2013, we other-than-temporarily impaired seven fixed-maturity securities. At December 31, 2013, forty fixed-maturity investments with a total unrealized loss of $5 million had been in an unrealized loss position for 12 months or more. Of that total, no fixed-maturity investments had fair values below 70 percent of amortized cost. There were no equity investments in an unrealized loss position for 12 months or more as of December 31, 2013. |

FAIR VALUE MEASUREMENTS | ||||||||||||||||||||||
Fair Value Hierarchy | ||||||||||||||||||||||
In accordance with accounting guidance for fair value measurements and disclosures, we categorized our financial instruments, based on the priority of the observable and market-based data for the valuation technique used, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2013, and ultimately management determines fair value. See our 2013 Annual Report on Form 10-K, Item 8, Note 3, Fair Value Measurements, Page 121, for information on characteristics and valuation techniques used in determining fair value. | ||||||||||||||||||||||
Fair Value Disclosures for Assets | ||||||||||||||||||||||
The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at March 31, 2014, and December 31, 2013. We do not have any material liabilities carried at fair value. There were no transfers between Level 1 and Level 2. | ||||||||||||||||||||||

We use actuarial methods, models and judgment to estimate, as of a financial statement date, the property casualty loss and loss expense reserves required to pay for and settle all outstanding insured claims, including incurred but not reported (IBNR) claims, as of that date. The actuarial estimate is subject to review and adjustment by an | |||||||||
inter-departmental committee that includes actuarial management that is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. The reserve for loss and loss expenses in the condensed consolidated balance sheets also included $52 million at March 31, 2014, and $67 million at March 31, 2013, for certain life and health loss and loss expense reserves. | |||||||||

We establish the reserves for traditional life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates, timing of claim presentation and investment yields, including a provision for uncertainty. Once these assumptions are established, they generally are maintained throughout the lives of the contracts. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. We base our assumptions for expected investment income on our own experience adjusted for current economic conditions. | |||||||||
We establish reserves for the company’s universal life, deferred annuity and structured settlement policies equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life policies contain no-lapse guarantee provisions.

Commitments And Contingent Liabilities | ' |
COMMITMENTS AND CONTINGENT LIABILITIES | |
In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving the company's insurance subsidiaries in which the company is either defending or providing indemnity for third-party claims brought against insureds or litigating first-party coverage claims. The company accounts for such activity through the establishment of unpaid loss and loss adjustment expense reserves. We believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, is immaterial to our consolidated financial condition, results of operations and cash flows. | |
The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such proceedings have alleged, for example, breach of an alleged duty to search national data bases to ascertain unreported deaths of insureds under life insurance policies. The company's insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such as claims alleging bad faith handling of insurance claims or writing unauthorized coverage or claims alleging discrimination by former associates. | |
On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial condition or results of operations. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, the resulting liability could have a material effect on the company's consolidated results of operations or cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote, is less than $1 million. |
